| Abstract: | The new algorithms to find out minimum circumscribed and maximum inscribed circle with computer are respectively introduced.The optimum direction and the distance of center movement can be determined by formula in every step of the algorithms.Therefore,the accurate posi- tion of minimum circumscribed circle and maximum inscribed one for real outline can be find out by a few of iterations. |
